However one strange thing that happened is we swapped the CPU power cable from the PCI Express /CPU connection on the PSU (TICK) to the dedicated CPU power connector (X), and while initially the PC would still crash at the same spots, when I reset the BIOS to optimise defaults, removing my current overclock, the system now seems stable.... we're still testing ( black Desert Online is running currently while I'm writing this post).

Surely that was the problem then, having the CPU cable plugged into the wrong connector on the PSU ?
 
The PSU has two useable CPU power connectors and some Mobos can use 2 x 8 pin power.

Either one should work, but the way they share OCP with the PCI-E and mobo 24pin is causing a problem. It still may be faulty, the OCP kicking in too low.

Thanks for all the help guys, yeah my friend is bringing the card back tomorrow, and we're gonna try one last thing, I did some reading about the PSU I have, and it's "Easyrail" system... Turns out that its not just 1 super rail but 4 separate 12v rails, so we're gonna try one last thing my friend suggested, which is to try powering the card from two separate PCI-E cables and spread the load across 2 rails as I have a good amount unused. Any thoughts on this idea?

I would always recommend doing this.
